[Live-devel] [Fwd: Re: trick mode index files: x86 and ppc]

[Daniel Robbins]

Ross,

Any ideas so far on the .tsx index differences? Just trying to figure 
out whether to certify our current build as "good enough for now" on 
PowerPC (it *does* appear to work, even with the .tsx files not 
matching) or whether there might be an upcoming patch in the next few 
days that I should wait for.

Regards,

Daniel
